General description

Caspase-8 (MACH/FLICE/Mch5) is a member of a family of cysteine-requiring aspartate proteases that participate in the intracellular signaling cascade leading to apoptosis, or programmed cell death. Caspase-8 is recruited to death-inducing signaling complex (DISC), CD95 (Fas/APO-1) and tumor necrosis factor receptor 1 (TNFR1) and is subsequently activated by proteolytic cleavage into two residues, p10 and p18. Active caspase-8 or the p18 subunit, is the first in the caspase signaling cascade, and it signals downstream caspases to eventually induce apoptosis.

Specificity

This antibody recognizes the active form (p18 subunit) of Caspase-8.

Immunogen

KLH-conjugated linear peptide corresponding to the active form of human Caspase-8.

Application

Detect Caspase-8 (active form p18 subunit) using this Anti-Caspase-8 (active form p18 subunit) Antibody, clone 2B12.1 validated for use in WB & IC.
Immunocytochemistry Analysis: A 1:500 dilution from a previous lot detected active Caspase-8 (p18 subunit) in etoposide-treated HeLa cells.

Quality

Evaluated by Western Blot in camptothecin-treated and untreated Jurkat lysates.

Western Blot Analysis: 2 µg/mL of this antibody detected the active form of Caspase-8 (p18 subunit) in 10 µg of camptothecin-treated Jurkat lysates. Untreated jurkat lysate exhibited no detection of active Caspase-8.
